ST10F269Z2T3 Description

The ST10F269Z2T3 is a member of the ST10 family of 16-bit single-chip CMOS microcontrollers from STMicroelectronics. It combines high peripheral functionality, improved I/O capabilities, and high CPU performance (up to 20 million instructions per second). Additionally, it offers high-speed RAM, single-voltage Flash memory, and PLL-generated clocks on the same chip.

Processing for ST10F269Z2T3 uses 0.35-m CMOS technology. On PQFP144 devices, the MCU core and logic are powered via a 5V to 3.3V on-chip voltage regulator (or 5V to 2.7V on TQFP144 devices). I/Os on the component operate at 5V and are provided by a single 5V supply.
